Is there no way to override the settings manually?
No. 25p is not part of the BluRay specification and therefore no pre-made matrices exist. If you want such functionality, you will have to use tools like TMPEGEnc that allow customization of their routines, even if they are out of spec. Still, even if you can encode it, players may refuse to play it due to incorrect stream flags, so it may not solve anything. Because of that, logically creating a H.264 file is your best option for this kind of thing.
Many thanks for the prompt reply!
I was afraid of that! I never found the 25fps progressive in any blu-ray specs.
Trouble is that we are preparing material for playback on a multi-display system of projectors that prefer files at 25fps (projectors operate at 50HZ, therefore smoother playback at 25 or 50fps playback - and 50 is out of the question!).
Being large-scale projections, I don't want to risk comb-effect from appearing (using interlaced material)...
TMPENG....ohhh....have been down this treacherous path before...
Mmh, if it's for projectors on a show, can't the technicians work based on 24p? Since for multiscreen it will be routed through a signal processor/ splitter anyway, it would offer to double frames every n cycles. From my own experience on tradeshows I know that these devices offer many such options to compensate for signal delays and sync issues over long cables, maybe it can work in your favor here as well. Or even better: The projectors can be set to 24p natively?
Many thanks Mylenium.... fact is we already have rendered an awful lot of things in 3D at 25 fps....grrrrrrr
It seems we will have to discuss a different format altogether with the technical company that will be projecting... (of the MPEG2 type, since the hardware prefers it...).
As for setting up the projectors to 24p, however nicely cinematic that would be, I don't think the playback system supports it. It is a bit of a headache this thing - and cannot be changed..
Back to the drawing board, then... many many thanks again, "may the frames be with you"!
